ZIPPY Compact 1500mAh 3S 25C Lipo Pack

Given that they're only 25C rated I was surprised that they don't seem to sag much under load. OK, they're not comparable to graphenes but even so, when pushed to the limit they drop fairly slowly, loiter at higher voltages and recover faster than some other, higher-'C' rated batteries.
Overall these are good value. If the low 'C' rating isn't an issue then save some weight, space and money and get these.

affordable!

Thanks again! Addicted to buying!

Been using these batteries for a while now and they are out lasting most of my other packs. Came well balanced out of the box and I'm still yet to have one puff and I run them quite hard. I would definitely buy more.

Great quality pack at an even better price. Note the recent change in size of this pack, now 21mm thick vice 17mm and 25g heavier than the original. Still a great pack but now not quite so compact.

Good quality, I use it on my race quad.

What's great about this battery is how thin it is. On many of my model designs, there's not much space for a battery, and this format makes a real difference. Without abusing the battery, I can get about 12-14 minutes in the air for my foam board biplane builds, which all weigh-in at just over 1kg. Considering the price that's very good value.

We are super happy with these batteries. we run all our racing drones, and video equipment on them, and they keep working, although we mistreat them again and again.

Good size for 250 fpv multirotor, the 25C discharge is enough for travelling and also good for rc plane as well.
